Turnkey dedusting plant for the asphalt mixing plant
Delivery description
In this RETROFIT project, the focus was on reusing components such as the raw gas pipeline, pipe screws, frequency converters and the control cabinet in order to minimize costs. This project was implemented by us on a turnkey basis up to commissioning.
Components
- Flat bag filter with large walk-in clean gas chamber
- mobile steel foundations
- Clean gas pipeline
- Fan
- Coarse separator
- surface mounted chimney
Operating principle
The raw gas is taken from the various emission sources and fed to the coarse separator via a pipeline. Below the coarse separator, the coarse dust fraction is transferred via a double pendulum flap into a tubular screw conveyor and transported to the hot elevator. The raw gas flows into the filter with the fine fraction and is cleaned at the filter pockets. The fines are also transported to a filler silo or filler tower via a double pendulum flap and tubular screw conveyor. The clean gas is then blown outdoors via the fan and the chimney.
